Note that that’s only when the drives have hit their rated program/erase cycles, meaning completely worn out but still functioning. Does not apply to drives with lots of life left in them, which is the vast majority of consumer drives.
From the linked pdf:
>In MLC and SLC, this can be as low as 3 months and best case can be more than 10
years. The retention is highly dependent on temperature and workload.
Interestingly, while heat can increase the rate of information loss (when drive is worn out), it can also decrease wear on the drive by making writes easier and less destructive to flash cells. The controller is still going to hate heat though.
